摘要
通过对某石化企业572名孕妇进行回顾性流行病学调查，结果：（1）暴露于混苯化合物的孕妇与对照组比较，孕周，出生体重，身长，经单因素t检验，差别具有显著性。（2）引入多个混杂变量，经多元逐步回归进一步分析结果提示：孕妇混苯化合物暴露是影响新生儿出生体重及身长的主要因素，而孕妇上举或搬运重物，在家被动吸烟，摄入蔬菜，饮用奶类和家务劳动对新生儿出生体重及身长也产生一定的影响。（3）经Logistic逐步回归分析，孕妇混苯化合物暴露对新生儿早产及出生低体重的影响，可使其相对危险度增加，与对照组比较差别具有显著性。
A respective study of 572 pregnant women was conducted for detecting the influ ence of benzol blends on fetal growth. The result showed: (1) The gestational weeks, birth weight and body length of groups exposed to benzol blend are significantly different from those of control groups. (2) The stepwise regression analysis on confounding factors indicated that the benzol blends had a main effect on birth weight and body length. We also found that there was a significant association of lift weight, passive smoking at home, intake of vegtables, drinking milk and housework with the birth weight and body length. And (3), the logistic analysis results showed a significant association of benzol blend with preterm birth and low birth weight.
